Coming attractions: all-electronic tolls on Golden Gate Bridge

Transportation officials on Monday put five message signs into place along Highway 101 in Marin County reminding drivers that the Golden Gate Bridge will switch to all-electronic tolls on March 27. There are nine changeable message signs now activated in Marin, San Francisco and Contra Costa counties, part of a campaign to make sure all drivers are aware of the big change in two weeks. The district has established a website — www.goldengate.org/tolls — to provide more information to drivers about what the switch will mean and how they can pay tolls. The sign above is on southbound Highway 101 in Novato.
